udev: also create /dev/disk/by-part{label,uuid} and gpt-auto-root symlinks

Browse Source 
The blkid we call in 13-dm-disk.rules also returns identifiers for
partitions based on which the /dev/disk/by-part{uuid,label} and
gpt-auto-root symlinks should be created in the same manner as we
already create symlinks for filesystem labels and uuids.

This is because we handle blkid calls and symlink creation under
/dev/disk ourselves in our 13-dm-disk.rules for device-mapper devices
for us to have more control over this process.

See also https://lists.freedesktop.org/archives/systemd-devel/2017-July/039220.html
and original report http://tracker.ceph.com/issues/19489 for
the exact case where these symlinks were missing.
